Hey all,
I am currently working on starting FLUENT in batch mode on Windows system. I already set up the .cas file with the GUI. Now I want to start fluent in background by submitting the journal file (the command I am using in the Windows Shell is "fluent 2ddp -t4 -hidden -i Test.jou). I already got it working, but as soon as I am trying to set boundary conditions e.g. x-velocity in the journal file, the initialization of the domain fails. My journal-file: ; Read case file /file/read-case FFF-fast.cas.h5 ; ; Define Inlet Velocity /define/boundary-conditions/velocity-inlet inlet no yes yes no 0 yes no 10 no 0 no 603.15 no yes 1 0.01 ; ; Write Boundary Condition file ;/file/write-bc BoundaryConditions ; ; Initialize the solution ; /solve/initialize/compute-defaults/velocity-inlet inlet /solve/initialize/initialize-flow ; ; Calculate 50 iterations it 50 ; ; Write data file wd example50.dat ; ; Exit Fluent exit yes After initialzing the flow the following error message appears in the trn-file Error at Node 0: interpolate_profile_field: thread 7: profile "" does not exist. Error at Node 1: interpolate_profile_field: thread 7: profile "" does not exist. Error at Node 2: interpolate_profile_field: thread 7: profile "" does not exist. Error at Node 3: interpolate_profile_field: thread 7: profile "" does not exist. ===============Message from the Cortex Process================================ Compute processes interrupted. Processing can be resumed. ================================================== ============================ Warning: An error or interrupt occurred while reading the journal file. Some commands may not have been completed. How to correct this error message and get fluent working? What does .h5 mean? Appreciate every help ![]() Regards, cfd123_ |

most likely the problem is here
Code:
/define/boundary-conditions/velocity-inlet inlet no yes yes no 0 yes no 10 no 0 no 603.15 no yes 1 0.01 put in console Code:
define/boundary-conditions find the proper command sequence for your case

.h5 is a container format used by other Ansys CFD programs. The format has existed for a long time, it just hasn't been the default for Fluent. Ansys now uses .h5 for all its CFD to harmonize file formats. To write the legacy .cas file you have to check/uncheck some boxes. It shouldn't matter though to 99.999% of users, it's just a container format.
You should do what has been suggested and type define/boundary-conditios in for your case and make sure you have all the prompts entered correctly for your case. Don't just copy and paste journals from the internet. If the problem still persists then you have a setup issue with your case... The error is Fluent is looking for a profile to map onto some boundary (I know not where). The profile name is blank. |
